Steaming spool



A ril 30, 1935. E. H. TOMPKINS STEAMING SPOOL Filed April 19, 1954 \NVENTOR ATTORNEY Patented Apr. 30, 1935 STEAMING SPOOL Emerson H. Tompkins, Waterbury, Conn., as-

signor to Scovill Manufacturing Company,

Waterbury, Conn, a corporation of Connecticut Application April 19, 1934, Serial No. 721,333 5 Claims. (01. 242-123) This invention relates to spools, and more particularly to a, sheet metal spool adapted. for use in the steaming and soaking of spooled material, such as silk, for use in the manufacture of tex- One object of this invention is to provide a metal spool of the above naturehaving a pair of concentric tubes supported at their ends in a pair of circular end heads, each head comprising a circular lining ring interlocked upon an end disc, said ring being provided with a large central aperture adapted to fit tightly over the end of the outer tube or drum of the spool, thus producing a sharp right-angle junction between a the lining ring and the outer drum without the use of solder as a fillet.

A further object is to provide a spool of the above nature in which the outer discs of the end heads are provided with a plurality of spaced lugs inturned from the body of the disc and radially arranged with respect to the axis of the spool, the outer edges of said inturned lugs having a tight engagement within the ends of the outer drum for reinforcing said drum against external crushing stresses.

A further object is to provide a spool of the above nature which will be simple and strong inconstruction, inexpensive to manufacture, easy to assemble and manipulate, compact, ornamental in appearance, and very efficient and durable in use.

With these and other objects in view, there has been illustrated on the accompanying drawing, one form in which the invention may be conveniently embodied in practice.

In the drawing:

Fig. 1 represents a side proved winding spool.

Fig. 2 is an end view of the same.

Fig. 3 is a longitudinal sectional view on a slightly enlarged scale, the view being taken along the dotted line 3-3 of Fig. 2, looking in the direction of the arrows.

Fig. 4 is a transverse sectional view, taken along the line 4-4 of Fig. 3, looking in the direction of the arrows.

This invention is an improvement over an application filed by Frederick R. Reutter, Serial No. 697,605, November 11, 1933, and owned by the same assignee.

Referring now to the drawing in which like reference numerals denote corresponding parts throughout the several views, the numeral generally indicates a metal winding spool e bodying the invention, said spool consisting of an outer cylindrical shell or barrel II, a pair of elevation of the imhaving its side edges provided with a pair of in- 5' turned longitudinal abutting parallel flanges IS, the outer junction seam of which is adapted to be filled with a line of solder a to provide a smooth flush surface.

The heads I? and i3 are identical in construe tion and each comprises an exterior disc-l6 and an interior fiat lining plate or ring H. The exterior disc i6 is ofi'set outwardly at its central portion to form an annular boss IS. The center of the boss i8 is to form a curved flange or hubl9, against which the ends of the spindle M are adapted to be spun over, as shown in Fig. 3. The aperture in the lining ring I? is of such size that the ring will slip over the ends of the barrel I I and have a substantially snug fit thereupon.

In order to affix the lining ring I? to the disc it, the peripheral section of said ring I l is curled over outwardly upon itself to form a round bead which is adapted to embrace, the outer edge 25 of said disc 16 in the manner shown in Fig. 3. The above construction not only forms a permanent fastening means between the ring l1 and the disc It to form the head units it! and I3, but also reinforces the strength heads. It also produces smooth round edges for said heads l2 and I3 over which the yarn or silk being wound upon the spool may easily slide without catching. It will be noted that the outside surface of the beads 20 lie in substantially the same plane as the central bosses l8, so that the spool will have a stable support when resting on a horizontal surface, this construction also permitting the spools to be readily stacked.

The lining ring I! and the disc I6 having been assembled as above described to form the unit heads l2 and 53, said heads will next be positioned on the opposite ends of the outer barrel II, and, as shown in Fig. 3, held in permanently attached position by spinning the ends 2| of the 45 spindle tube #4 outwardly around the hubs l9, H, as described above.

In order to further strengthen the construction of the spool and increase the resistance of the barrel H to inward collapsing forces, such as 5 might be caused by an excessive shrinkage of the material wound upon the spool when drying, the end discs Hi, 16 are provided with a plurality of substantially broad integral inwardly extending flat lugs 22 struck inwardly from the body of the 5 apertured and bent inwardly 15? and stifiness of said disc 16 and leaving a corresponding number of openings 23 therein.

The lugs 22 are preferably equally spaced in a circular formation around the axis of the spool and are radially positioned with respect to said axis in such a manner that the outer horizontal edges of said lugs are adapted to tightly engage a plurality of rows of spaced apertures 25 for 1 permitting the yarn on the spool to be freely exposed to the action of the steam or other fluid to which it is to be subjected. The steam is adapted to pass into the interior chamber of the spool through the openings 23 in the end discs l5, and also'through an aperture 28 in the interior of the spindletube l 4.

While there has been disclosed. in this specification one form in which the invention may be embodied, it is to be understood that this form is shown for the purpose of illustration only, and that the invention is not to be limited to the specific disclosure but may be modified and embodied in various other forms without departing from its spirit. In short, the invention includes all the modifications and embodiments coming within the scope of the following claims.

Having thus fully described the invention, what is claimed as new and for which it is desired to secure Letters Patent, is:

1. In a winding spool, a tubular barrel, a pair of transverse end discs having outwardly offset central bosses to form seats for receivingthe opposite ends of said barrel, said bosses having concentric co-axial apertures, a spindle tube engaging in said apertures and connected to said discs for holding the latter in assembled position against the ends of said barrel, said discs having a plurality of spaced longitudinal lugs with their planes radially positioned relative to the axis of said barrel struck inwardly from the body of said bosses, the edges of said lugs engaging said barrel, whereby said lugs will support the interior wall or" said barrel against compressive forces.

2. In a winding spool, a tubular barrel, a pair of transverse end discs having outwardly offset central bosses to form seats for receiving the opposite ends of said barrel, said bosses having concentric co-axial apertures, a spindle tube engaging in said apertures and connected to said discs for holding the latter in assembled position against the ends of said barrel, said discs having a plurality of spaced longitudinal lugs with their planes radially positioned'relative to the axis of said barrel struck inwardly from the body of said bosses, the edges of said lugs engaging said barrel, whereby said lugs will support the interior wall of said barrel against compressive forces.

3. In a winding spool, a tubular barrel, a pair of transverse end discs having outwardly offset central bosses to form seats for receiving the opposite ends of said barrel, said bosses having concentric co-axial apertures, a spindle tube engaging in said apertures and connected to said discs for holding the latter in assembled position against the ends of said barrel, said discs having a plurality of spaced longitudinal flat lugs with their planes radially positioned relative to the axis of said barrel struck inwardly from the body of said bosses, the edges of said lugs engaging said barrel, whereby said lugs will support the interior wall of said barrel against compressive forces.

4. In a winding spool, a tubular barrel, a pair of transverse end'heads, said heads comprising a pair of discs having outwardly offset bosses abutted against the ends of said barrel and a pair of lining rings lying flat against the interior surfaces of said discs beyond the circumference of the barrel, said rings being snugly fitted over said barrel, said discs having a plurality of spaced longitudinal lugs struck'inwardly from the body of said disc with their edges engaging said barrel and having their planes radially positioned relative to the axis of said barrel so that the ends of said barrel will be securely held between said lining ring and said lugs.

5. In a winding spool, a tubular barrel, a pair of transverse end plates secured at the ends of said barrel, said plates having longitudinal inwardly projecting fiat lugs extending into the ends of said barrel with their edges engaging said barrel, the planes of said lugs being in a radial position relative to the axis of said barrel so that the outer edge of said lugs will engage the interior surface of said barrel and support the edges thereof against collapse due to external compressive forces.
